To whmn it ntay concern: I

Be it known that 1, JOHN ROGER, a subject; of the King of Great Britain, residing at Denver, in the county of Arapahoe and State of Colorado, have invented new and useful Improvements in Separators, of which the fol;

lowing is a specification.

This invention relates to certain new and.

useful improvements inseparators, and it'is particularly adapted for the separation of va-' rious kinds of materials, such as ore or the like.

The invention aims to construct a separator or what may be termed a vibrating screen for separating or screening various kinds of materials by a vibratory motion.

The separating or. screening of material, particularly through fine screens, is somewhat a vexed problem, and for such purpose the employment of circular screens have been almost exclusively used. The objectionto theiruse. is that they are large, cumbersome, and

inaccessible and haveusually been operated" to give to thematerial a bumping motion to cause thefine material to pass through the screen-openings, and owing tothis bumping action the material would travel forward readily and the particles which are just large vthe material to fall as the screen makes its back stroke. By such an arrangement the material is advanced by a series of impulses instead of by a direct rubbing contact with the screen-surface, thereby greatly decreasing the wear on thescreen plate or cloth and also tending to keep the screen-openingsfree during the passage therethrough of the material.

The invention further aims to construct a separator or vibrating screen which shall be simple in its construction, strong, durable,

efficient in its operation, comparatively inexpensive to set up; and to this end it consists of the novel combination and arrangement of U parts hereinafter more specifically described,

illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention' in detail refererenoe is had to the accompanying drawings,

.wherein like numerals'of reference indicate corresponding parts throughout the several 'views, and in which-,-

Figure' 1 is a central vertical section of my improved separator onscreen, and Fig. 2 is an end elevation. .Fig. 3 is a detail view of the-operating-shaft and its eccentrics. Fig. 4 is a perspective view of the screen-frame, partly brokelrmvay. Fig. 5-is a plan of the mechanism for adjusting the screen to various inclinations.

Referring to the drawings by referencenumerals, the supporting or main frame is formed with a base 1, having integral therewith at each end thereof avertical standard 2, provided with an outwardly-extending offset 2. Each of the standards 2 at the top thereof is provided with a journal-box 3, in which is journaled the drive-shaft 4, extend ing across the main frame. The latter is constructed, preferably, 'ofcast metal, although other material may be employed, as well as other forms than that above referred to. Thedrivc-shaft 4: extends from one side of the frame and carries the fast and loose pulleys5 6,'resp-ectively, which are suitably connected to a power source.

The reference-numeral 7 denotes the bolts or other means for securing the sections of the journal-boxes 3 together. These bolts may extend in any suitable manner through the sections of the box.

The reference-numeral 8 denotes a lubricating device mounted upon the journalboxes 3.

Adapted to be arranged, within the main frame,as well as'operatingbetwee'n the standards 2, is a pair of substantially V-shaped supports 9 10, which areclosedat their top of the top ofeach of the supports .9 10 is formed an eccentric-box 1:3, in which is journaled the eccentrics 14 carried by the shaft.

a. The reference -numeral denotes the bolts or other means for connecting together the sections of the eccentric-boxes. These bolts may extend through and be secured to the sections in any suitable manner.

The shaft 12 carries a forwardly-projecting intcriorly -screw-threaded coupling 16, secured thereto approximately centrally thereof and is adapted to receive one end of an adjusting bar 17. This adjusting bar is screw-threaded and extends through a rockshaft 18, and, further, carries the fasteningnuts 19, one on each side of the shaft 18. The rock-shaft is journaled in a bearingbracket 20, secured to the base 1 of the main frame in any desirable manner. The bar 17 is adapted to adjust the vibratory frame to any desired angle, causing thereby the adjustment of the screen, to be hereinafter described.

The reference-numerals 21 22 denote a pair of longitudinally-extending channelbars, and the reference-numeral 23 a horizontallyextending channel-bar, which is connected in any desirable manner to the forward end of the channel-bars 21 22. The channel-bars are attached to the plate 2%, the latter being secured to the supports 9 10 and forms the bottom of the screen-frame.

Mounted upon and secured to the channelbars 21 22 23 is the frame carrying a screen plate or cloth 25. This frame is formed of two pairs of longitudinally-extending side bars 26 27, a pair of horizontallyextending front bars 28 29, which are secured to the forward ends of the bars 26 and 27, and a longitudinally-extending bar 30, secured to the rear end of the bars 26 27. The screen plate or cloth 25 is secured between the sides and front bars 26 27 28 29 and upon therearbar30.

The refercnce-numerals 31 32 denote the sides and front plates, respectively, of the screen-frame. The former are secured to the side bars 26 2'7 and project above as well as rearwardly therefrom, and the latter is secured to the front bars 28 29 and project above the same.

Mounted upon and secured to the channelbars 21 22 and also to the rear bar 31 is an angle-iron 33, and against the lower portion of said angle-iron 33 is placed the top edge of an inclined delivery-chute 34, the latter being secured to the side plates 31 and also to the angle-iron The reference-numeral 35 denotes an angleiron secured to one end of the supports 9 10 to prevent the screenings from fallin g within the housing or frame as theyleave the bottom plate 24.

Arranged at the rear of the screen-frame is a receptacle 36, divided into two compartments 37 38, the former to receive the screenings from the bottom plate 2% and the latter to receive the separated material from the screen plate or cloth through the medium of the delivery-chute 34:, which is so arranged as to extend CV61 the compartment 38.

The reference-numeral 39 denotes a supplychute arranged above the screcn-frame at the forward end thereof.

The operation of the separator is as follows: It will be evident that on the shaft being rotated through the medium of the fixed pulley the eccentrics upon the shaft will impart to the supports 9 10 and screen a vibrating motion due to the eccentricity of the eccentrics and their boxes, the screen in the meanwhile being adjusted to the angle desired, depending on the kind of material to be separated. The material to be separated or screened is fed to the surface of the screen plate or cloth through the medium of the chute 39, and the movement of the screen causes the material to travel toward the other end thereof, the fine material passing through the perforations in the screen. plate or cloth and dropping onto the bottom plate 24. This fine or separated material will also travel forward with the movement of the screen until it reaches the end of the bottom plate, where it will pass directly into the receptacle 3(5. The coarse material similarly passes over the surface of the screen plate or cloth, and by means of the chute 34 it will pass into the compartment 38 of the receptacle 36. It will be evident that when the shaft is operated, the vibratory motion given to the supports 9 10, and the screen the material will be thrown slightly off the screen and forward and that the same will fall upon the screen on the back stroke thereof. By such an operation the material is advanced by a series of impulses instead of by a direct rubbing contact with the screen plate or cloth, greatly decreasing the wear on the same as well as tending to keep the screenopenings free from the material, so the operation of separating or screening will not be retarded in any manner. It will also be evident that through the medium of the adjusting-bar 17 and the shafts 12 and 18 the supports 9 10 and the screcn-frame can be adj usted to any desirable inclination.

It is thought that the many advantages derived from the separator or vibrating screen constructed in accordance with the foregoing specification, taken in connection with the accompanying drawings, will be readily understood, and it will also benoted that minor changes may be made in the details of 0011- struction without departing from the general spirit of my invention.
